METALLIC SHEET-ROOFING.

Specication of Letters Patent.

IApplication filed Tnlv 16. 1907. Serial No. 384.052.

To all whom it may concern:

Be it known that JOHN T. BURRIss and OLIVER G. BURRrss, citizens of the United States, residing at Anderson, in the county of Anderson and State of South Carolina, have invented certain new and useful .Im-

provements .in Metallic vSheet-Roofings, of

e scribed in this specication, and pointed 'out in the claims hereunto attached.

Referring to the accompanying drawings, Figure 1, is a erspective view of three of the shingles and t ree of the nail stirrups joined together, part of the shingles being broken away, and one of the stirrups being shown in dotted lines. `Fig. 2, is a `face view vof three of the shingles partly broken away, the remaining parts fin position; also showing two of the stirrups, one being in dotted lines.

Fig. 3, is a cross sectional view of Fig. 2, on the line 3,- 3. l

Like letters of reference indicate the same partsin-all the-figures. e

Oui1 invention is described as follows:-

Referring to the drawings, the numerals 1, 11 and 12, represent the shingles and 2, the stirmps. The right -hand edge of each shingle, in reading the drawings from left to right, is turned 1nto a spiral curve 3, the

bend rising upward, from the face of the shingle, .turning gradually tol theiright, then downwardly to the left, and finally terminating in an u-pturned edge nearly on a vertical line with the face of the shingle, but slightly to the right, thus forming a hook 4. The left-hand edge ofthe shingle is also turned into a spiral curve 5, somewhat in the shape :v of a C, 1ts locking arm 6,'tern'1inating about the center of said curve, and being on a line .parallel with the face of the shingle, the

shingles being exactly alike, vorrtwins. v Said roofing is provided'wi'th a sufficient number of stirrups 2; the left-hand end of each stirrup, in reading the drawings, usually two stirrups to each shingle, is'straight and is rovided with nail-holes, oneytwo or more, Y y means` of which the said stirrups andl shingles are secured to the roof; the righthand end of each stirru is formed into a siral curve 7, by being rst bent upwardly, t.

en forwardly, then downwardly, then inwardly and then upwardly again, terminating in an upturnedv locking-arm 8, conforming as near as ossible tothecurve 3, of the lsh ingle','and iipnally locking in against the locking-arm 6, of the curve 5. Each shingle is provided, at its upperfend, with nail holes 9."

The roofng'is built from the eaves upwardly, and from right to left, and` is applied A as follows-z First, the shingle 1-2, is applied, then the stirrup 2 slipped into the curve 5, with its locking-arm 8, locking against the locking-arm 6, of the curve 5; then the shingle 1, is slipped on over the curve y7, o'f the 'stirrup, and the curve 5, of shingle 12, its

locking-arm 4, terminating in the center of said three spiral curves. Each shingle and each stirrup is made sepmay be adapted to any roof, no matter how long or how wide. y

Among the many advantages of this roof is that every stirrup is covered by the shinarately; thus it will be seen that this roofing gles and every nail 1n said stirrups and shingles is protected from the weather.

The spiral curves enable the operator to apply the roofing easily and qulckly, and these curves give such elasticity to the shingles that they will not cup in hot, or be strained in cold weather, and the lockingarms so lock the edges of the shingles that by no possibility, can they come loose by accident, or changes of atmosphere.

It is obvious that roofing of this class is susceptible of many variations of form in different details, and we reserve the right to make any such changesand modiiication as may be resorted, to without departing-,from the spirit of our invention.v

lThev face of each shingle is formed into any desired ornamental figure, by the clamping or embosslng process for the purpose of stiffvening and 'strengthening'the roof. The iig- .ure may be of any desiredfform, but something like the figure shown `1s preferred.

A Having describedour invention', what we claim as new and desire tosecure`by Letters l. The above "described-shingles or roong plates and stirrups formed'of sheet metal, the right-hand edge of each shingle turned into a spiral curve 3, the bend rising upward f' from the face ofthe shingle, `thenturnlng to L the right, then downwardly and to the left and finally terminating in a locking-arm 4, nearly on a vertical line to the face of the shingle, the left-hand edge turned into a spiral curve 5, -somewhat in the shape of a C, having a locking-arm 6, terminating about the center of said curve and being on a line i arallel with the shapeof the shingle, the eft-hand end of each stirrup straight and rovided with nail holes, the right-hand end ormedinto a spiral eurie 7, terminating in' Vvabove described shingles andy stirrups, the

right-hand edge of eaeh shingle turned into a spiral-curve 3, the bend rising Aupwardly from the face of the shingle, then turning to the right, then downwardly and to the left, terminating in an upturned locking-arm 4, nearl on a vertical line to the face of the 425 shing e, the left-hand edge of said shingle shape of a C, having an inwardhY turned locking-arm 6, terminating about the center of said curve; a stirru 2,its curve 7, and locking-arm 8, sli ped lnto the curve 5, with its looking-arm oeking against the inside face of the locking-arm 6, of the curve 5, as lsaid stirrup and sheet are brought into the same plane said stirrup and shingle being 'secured to the roof by nails ,a twin shingle 1, slipped over the curve 7, and arm 8, of the stirrup and curve 5, and arm 6, of the shingle 12, its looking-arm 4, terminating in the eenter of said three spiral curves, said shingle -completely covering said stirrup, substantially as shown and described and for the purposes set forth.
